v0.2.0 — mcp 2.x, and the one removal that needed new code

The mcp 2.x migration — the "separate work" that 0.1.2 deferred when it pinned mcp<2 to stop the broken installs.

FastMCP → mcp.server.mcpserver.MCPServer, with Image moving alongside it. The dependency moves to mcp>=2,<3 rather than widening to <3: this package imports mcp.server.mcpserver, absent in 1.x, so a range spanning both majors can resolve to a version that cannot import the server. That is precisely how dependabot's mcp<3 proposal (#7) broke the build, and why it was closed rather than merged. mcp 2.x requires Python >=3.10, exactly this package's floor, so the support matrix is unchanged.

The one removal that needed new code

create_connected_server_and_client_session is genuinely gone from mcp.shared.memory — the single change in this migration that was a removal rather than a rename, and the reason #7's CI failed for a second reason beyond the server break.

The replacement is mcp.client.Client, which accepts an MCPServer directly. It is better than what it replaces on two counts: no reaching through the private _mcp_server attribute, and the context manager initialises the session so the explicit initialize() call disappears. It remains a real client over in-memory transport rather than a direct call into the tool functions, which is the point of that test.

Version drift

__version__ now reads from installed metadata instead of being a fourth hand-maintained copy. test_packaging.py already guarded all four sources — it exists because this repo once shipped __version__ 0.1.0 while everything else said 0.1.1 — so this removes a source of drift rather than replacing the check that catches it. server.json and CITATION.cff cannot be derived and are still asserted.
